CAR TRUCTURE.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed March 30,1907. Serial No. 365,484.

To all whom it may concern:

Be it known that I, WILsoN E. SYMoNs, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Gar Structure, of which the following is aspecification. I

This invention relates to car structures, and more particularly to theunderframing for car bodies.

One of the principal objects of the present invention is to provide anend sill composed wholly or partially of metal, said sill being strong,and practically indestructible, in order that it will withstand therough usage and hard strains incident to this type of structure, andfurthermore having effective means, whereby the longitudinal sills andthe car siding can be secured in place.

In the accompanying drawings:Figure 1 is a plan view of one embodimentof the invention. Fig. 2 is an end view of the same. Fig. 3 is a crosssectional view. Fig. 4 is a side elevation of one of the joints betweenthe sill sections. Fig. 5 is a detail perspective view of one of theclamping plates. Fig. 6 is a crosssectional view through the structureshown in Fig. 4. Fig. 7 is a detail horizontal sectional view throughone of the plates, showing the particular construction of the spurs.Fig. 8 is a detail perspective view of a slightly modified form ofconstruction. Fig. 9 is a detail view of another modification.

Similar reference numerals designate corresponding parts in all thefigures of the drawings.

In the embodiment illustrated, the end Bill of the car comprises ametallic shell preferably, though not necessarily composed of cast steeland having an upper wall 10, a lower wall 11, and a rear wall 12 thatconnects said upper and lower walls. The rear wall is provided with setsof spaced rearwardly extending ears 13, and between these ears, mortisesl l are formed in said rear wall. The front side of the shell is open,but the upper and lower walls 10 and 11 are preferably provided withoppositely disposed inwardly extending flanges 15 that terminate shortof each other. Other inwardly extending flanges 16 are carried byintermediate portions of the upper and lower walls 10 and 11, andconstitute stops, as hereinafter explained.

The end sill can be employed under certain. conditions, as thusconstructed, but there is preferably located therein, a wooden core 17,which fits snugly between the upper and lower walls 10 and 11 and theflanges 15 and 16. This core has on its outer side a longitudinal rib 18that extends between the flanges l5, and projects from the open side ofthe shell. In practice, the core may preferably be composed of two ormore sections driven through opposite ends of the shell. As shown inFig. 3, the rib 18 constitutes convenient means to which the siding 19can be nailed, as shown at 20. Moreover, it will be evident that thisrib projecting beyond the outer face of the shell, serves to space thesiding therefrom. v

The longitudinal sills, designated 21, have their ends fitted betweenthe cars 13 of the different sets, to which cars, they are secured bytransverse bolts 22. The said ends of the longitudinal sills arefurthermore provided with tenons 23, which tenons engage in the mortisesl4, and project into the shell, as illustrated in Fig. 3. It will beobserved, however, that said tenons terminate short of the verticalplane of the flanges 16, and inasmuch as the rear side of the core 17 isabutted against the outer sides of said flanges, the tenons are spacedfrom the core. The longitudinal sills 21 are each preferably constructedof two or more sections, these sections being arranged end to end, andhaving a broken joint 24 between them. In order to effectively securethe sections together without weakening the sills by a plurality ofcomparatively large vertical bolt openings therethrough, the followingmechanism is preferably employed. Clamping plates 25 are located onopposite sides of the sections and bridge the joints between them. Theseplates are provided on their sides with inwardly projecting spurs 26,which spurs are pointed, and have certain of their sides, as 27perpendicular to the inner face of the plate, while the opposite sidesare arranged at an inclination, as shown at 28. The spurs that engage inone 'of the sections have their corresponding faces disposed inperpendicular relation, as described, while those that engage in theother sill section have their opposite faces perpendicular. This it willbe thought will be clear by reference to Fig. 7. The spurs are embeddedin the sections, and the plates are held in position by transversehorizontal bolts 29 that pass through said plates and through thesections. Preferably a single and comparatively small vertical bolt 30extends through the overlapping ends of the sections.

In one embodiment of the invention, the clamping plates are providedalong their lower edges with longitudinal flanges 31, which extendbeneath the sills. These flanges are preferably provided with dependingeyes 32, to which the brake rigging or portions thereof may be securedif desired. The flanges 31 are not on tirely essential, and may bedispensed with, as illustrated in Fig. 8, wherein a plate 33 isdisclosed having the usual spurs 34. Plates of the character shown inFig. 8 are particularly useful where the joints between the sillsections are located over the transoms or needle beams of the truck.These plates are preferably of cast steel, though they may be of iron orwrought longitudinal sills are shown substantially side by side,

because of the cutting away of the said sills, it will be evident tothose skilled in the art, that in practice these joints or splices aredisposed in staggered relation in order to preserve the strength of theunder frame as a whole.

An under-frame for car bodies is thus constructed, that is very strongand durable, the metal is practically indestructible, and while wood mayand is preferably employed as a core, this wood need not be of the highand expensive grade that is necessary for the ordinary end sill.Moreover, it will be evident that the ordinary siding and longitudinalsills may be effectively secured to the end sills. While thelongitudinal sills are shown of wood, and can be made of comparativelyshort sections, still it will be observed to those skilled in the art,that metallic longitudinal sills may be employed in connection with theend sill set forth. I

From the foregoing, it is thought that the construction, operation, andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction, may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.
